Thanks @apps. The same caution that you expressed about other social networks should also be used when searching newspapers and magazines. If you want to straight-up reprint the content, you have to ensure that it is no longer copyrighted. The protection period is shorter than it is for books (at least in the United States), but it can get tricky to determine, especially if you are from another country where the period may be longer or shorter. I suggest just using the content as a starting point and give it a full re-write and update it for modern times.
